There are radial bands installed between the bottom and the sleeve. The bands are fixed by one edge portion on the sleeve portion bent inside the body from the side of its surface facing the bottom, and the second edge portion is fastened to the bottom. The middle portion of the bands forms loops located between the bottom and the sleeve. There are hinges for installing the process wedge therein and having a length equal to the perimeter of the cross-section of the process wedge that is interfaced therewith. The edge portion of the bands can be provided with tails, the length of which allows them to be fastened together.
